tl;dr Is it possible to install ,config and use OpenWrt/DD-WRT firmware on a wireless router with no Ethernet connectivity?
(serial and WiFi working)
I've got a TP-link TL-WR841N router which had his Ethernet ports fried by an electric surge.
The router WiFi link still function, just no Ethernet connectivity of any kind.
I want to re purpose the router hardware so I can establish a serial communication over WiFi.
I read about the option of installing custom firmware to the route such as OpenWrt with net2serin order
to enable his on board serial port. I'm looking for someone who did this kind of hack before for some advice.
I can install OpenWrt by connecting to the router web interface through WiFi,
but cannot use Ethernet to continue with the setup afterwards.
will the serial interface or WiFi connection be working right after OpenWrt installation?
or if not, can I preconfig the OpenWrt image to work right out of the box?
The same questions for DD-WRT.
